3512E Tier 4 / IMO III

3512E Marine Propulsion Engine (U.S. EPA Tier 4 Final)

3512E Marine Propulsion Engine (U.S. EPA Tier 4 Final / IMO III)

DESCRIPTION

The 3512E marine propulsion engine is now available in a wide range of ratings that meet U.S. EPA Tier 4 Final and IMO III marine emissions regulations. As the commercial marine industry adjusts their operations to meet U.S. EPA Tier 4 Final and IMO III emissions standards, Caterpillar Marine has introduced a solution built to maximize performance while meeting regulations. Caterpillar's combination of a fuel-efficiency-optimized engine and a selective catalytic reduction (SCR) aftertreatment system is a solution that not only reduces NOx emissions, but can also lower a customer's owning and operating costs in the process.
